Title: Computerized magnetic resonance analyzer
Inventor: RONARUDO JIEI UEINSUTOTSUKU
IPC: G01R33/32
Filed: 1992-12-28
Abstract: PURPOSE: To detect the deviation between a material being tested and a reference material by radiating a prescribed electromagnetic wave for test to the material and comparing the obtained response with an expected response. CONSTITUTION: A test pattern signal from a modulator 16 is supplied to a primary exciting coil 22 so as to make the coil 22 generate an electromagnetic field for test. A material 24 to be tested is placed in the coil 22 and a secondary coil 26 detects an electromagnetic field generated in a test chamber 20. The output signal of the coil 26 is compared with the test pattern signal by means of a comparator 30 through a low-pass filter 28. The difference signal indicating the difference between the signals is amplified by means of an amplifier 36 and supplied to an electronic switch 38. The switch 38 selects either an external signal EP-IN or the output signal of the amplifier 36. The selected signal is amplified by means of an amplifier 42 and supplied to two evaluation channels.  The obtained response resonance spectrum is compared with a test pattern which is estimated to be obtained and conclusions are drawn from the difference between the spectrum and pattern.

Abstract: PROBLEM TO BE SOLVED: To guarantee high deceleration of a vehicle, to avoid a danger of a rear-end collision, and to enhance safety by generating large braking pressure by reducing a starting threshold value of an automatic braking process when confirming that an interval to a preceding vehicle is less than a critical value. SOLUTION: Whether or not an interval Dist to a preceding vehicle is less than a critical valve G1 using a threshold value decided according to a speed of a vehicle, is investigated (stage [S] 101), and when it is less than the critical value G1, a starting threshold value AS of an automatic braking process is decided by multiplying an initial threshold value 50 by a factor F (S102). Whether or not a braking pedal operation speed Vbp of a driver exceeds the starting threshold value AS is investigated (S103), and in the case of NO, whether or not the interval Dist to the preceding vehicle is larger by a prescribed valve DG than the critical value G1 is investigated (S104).  When it exceeds the starting threshold value AS, braking pressure larger than braking pressure in a position of a braking pedal is taken out (s106), and whether or not it satisfies a stopping stage reference of the automatic braking process is investigated (S107). In the case of NO, braking force is increased or maintained (S106), and when it is satisfied, the braking pressure is reduced (S108).
